Backfire device

Hello, I'm offering you a backfire device I bought about a few months ago and the electrical wiring for the device has been modified to over 180, the price of the device only hasn't changed, but I haven't tested it on the motor yet; it was installed and still complete, I just need to connect a wire to the coil or distributor but I couldn't find anyone to do it. Also, the device has a quick disconnect feature so you can easily remove and reinstall it whenever you want. The device fits most cars except diesel and turbocharged ones, and pollution caps must be removed. I bought the device for 1200 and selling it for offers, minimum offer is 700 because it's worth it, and the sale is permissible, God willing, and may God bless us all.
